Croatia hydraulic cylinder,rack cylinder manufacturer,rack cylinder
(Croatia rack cylinder,produced by Hengyu Hydraulic Co., Ltd）
rack cylinder are widely used in Croatia，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed rack cylinder for customers from Croatia.
Most of the failure of the rack cylinder is because there is a foreign body in the rack cylinder into the failure of the rack cylinder, the most problematic is that it is difficult to determine when the foreign body is into the rack cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.
rack cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.
The rack cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the rack cylinder should pay attention to: the operation should be as far away from the rack cylinder as possible, to avoid falling objects, knocking, rubbing the rack cylinder coating. When cleaning the rack cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the rack cylinder when the oil temperature exceeds 70 ° C.
The advantages and disadvantages of the rack cylinder: the surface of the rack cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the rack cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.
What is the difference between hydraulic piston cylinder and plunger cylinder?
The force surface of the piston cylinder is a rod cavity and a rodless cavity, and the force surface of the plunger cylinder is the plunger, the spring return single-acting piston cylinder can also rely on the external force of the spring to achieve return, the double-acting piston cylinder can produce tension, and the plunger cylinder only produces thrust without tension.
How to distinguish the size of hydraulic cylinder cavity?
The hydraulic cylinder has a rod cavity and a rodless cavity. The rod cavity is the cavity that the piston rod extends out. The rod cavity is of course small due to the existence of the piston rod. That's just relative.
